new to this forum but i've been browsing it alot trying to solve this problem i've been having with my truck. 97 powerstroke seems to be defueling. just no get up and go. i've gotten a few codes from it, I had a p0472. messed with the wiring in there, now I have a p0471. can't figure it out. tube is clean and the sensor was replaced. ebpv is deleted. tried the dongles for the ebps and they've done nothing. no cel on, just no power. usually drives kinda well the first 10 seconds after I start it. as far as I can tell there are no exhaust leaks. any ideas?

I have a buddy w/ a snap on scanner. I'll get this from him when I can. I wouldn't have other problems if I had a bad injector? she idles perfectly and doesn't smoke whatsoever other than start-up. thanks man.

the motor only needs fuel and air. Clogged fuel filter or bad fuel pump "in the center of the motor can do it."
The oil pressure from the hpop is also important, to get the fuel into the cylinders. I would assume a bad injector would cause a skip but not always.
The scanner will test injectors and tell you about hpop issues. You will need a mechanical gauge to test fuel pressure

Theres a screen on the fuel line(actually in the fuel bowl) where the fuel comes in. I dont have one on my superduty but your truck has this screen, it needs to be cleaned off at times. The crap you had to clean out of the bowl had to pass thru this screen. Some
o-rings will have to be purchased to take the bowl apart. and reassemble it. I would start there cause its cheap and good maintenance. Bob guzzle has themReplacement O-rings for Ford Diesel Engines real nice guy, will answer questions and has all the O rings you can ever need. Do a thread search here on this screen that you need to clean

check your MAP and the hose as well as the fitting in the engine, these commonly plug up with soot. Assuming you are not smoking when you floor it this is more than likely the issue cause the PCM/IDM will not fuel without boost readings
